old servos with new electronics
 

Can I use old servos and use with newer radio systems? I have airtronics 94158, and 94157 that I used in an old Ofna nitro car years ago. They were really pricey and they are in great shape.

So long as they can handle the voltage you run, sure.

They are digital but you have to try if they can run on higher speeds otherwise you shouls set to normal servo's
